Abstract
The influence of the undulation of the sensor is analyzed.A new concept of spatial correction of the sensor is brought out.The conclusion shows that within the range of about 10 m of the undulation,the maximum influence value can be about 10 nT.So the spatial correction must be introduced to diminish the influence of the undulation of the sensor.The correction method is studied,and the correction steps are given.
